This was the whole problem with the case. It's like Greer heard evidence 3 to 2 that the world was flat. He threw out testimony that he thought was biased or wrong and then ruled that the world was flat.
Thereafter, no matter how much evidence was presented that the world was round, it just didn't matter, as Greer had already declared it to be legal fact that the world was flat.
Judge Greer made the decsion about this case before it was heard, that is clear.
